Motion Controller Axis input values over scale in increments of 2

Motion Controller Axis input values over scale in increments of 2

Description

The Axis input values for SteamVR motion controllers will increase exponentially by 2 from the moment the editor starts and every time the user enters VR Mode or does a Launch On (eg. Entering VR Mode one will increase the input axis value -4 to 4, -6 to 6 etc.)

This does not occur with the Oculus Rift S

Steps to Reproduce

Setup SteamVR Device

Create a New Virtual Reality Template

Open the Entry level Level blueprint

Create a print string to print the motion controller Thumbstick X-axis to screen

Add an Event Tick node

Pull off of Event Tick and create a Print String node

Pull off from "In Sting" in the Print String node, disable context sensitive and Search for MotionControllerThumbRight_X then select the Input Axis Value.

Enter VR Preview

With the right motion controller

If using the Index move the joystick left to right

If using the Vive wands slide your thumb across the track pad from left to right

Results: The values between the two axes will be -2 to 2 (Left to Right respectively).

Expected: The values between the two axes will be -1 to 1 (Left to Right respectively).
